Among the merits of federalism are that it promotes policy innovation and political participation and accommodates diversity of opinion. On the subject of policy innovation, Supreme Court Justice Louis Brandeis observed in 1932 that “a single courageous state may, if its citizens choose, serve as a laboratory; and try novel social and economic experiments without risk to the rest of the country.”^[1]

What Brandeis meant was that states could harness their constitutional authority to engage in policy innovations that might eventually be diffused to other states and at the national level. For example, a number of New Deal breakthroughs, such as child labor laws, were inspired by state policies. Prior to the passage of the Nineteenth Amendment, several states had already granted women the right to vote. California has led the way in establishing standards for fuel emissions and other environmental policies (Figure). Recently, the health insurance exchanges run by Connecticut, Kentucky, Rhode Island, and Washington have served as models for other states seeking to improve the performance of their exchanges.^[2]

Another advantage of federalism is that because our federal system creates two levels of government with the capacity to take action, failure to attain a desired policy goal at one level can be offset by successfully securing the support of elected representatives at another level. Thus, individuals, groups, and social movements are encouraged to actively participate and help shape public policy.

The system of checks and balances in our political system often prevents the federal government from imposing uniform policies across the country. As a result, states and local communities have the latitude to address policy issues based on the specific needs and interests of their citizens. The diversity of public viewpoints across states is manifested by differences in the way states handle access to abortion, distribution of alcohol, gun control, and social welfare benefits, for example.

Federalism also comes with drawbacks. Chief among them are economic disparities across states, race-to-the-bottom dynamics (i.e., states compete to attract business by lowering taxes and regulations), and the difficulty of taking action on issues of national importance.

Stark economic differences across states have a profound effect on the well-being of citizens. For example, in 2014, Maryland had the highest median household income ($73,971), while Mississippi had the lowest ($39,680).^[5]

There are also huge disparities in school funding across states. In 2013, New York spent $19,818 per student for elementary and secondary education, while Utah spent $6,555.Governing.^[6]

Furthermore, health-care access, costs, and quality vary greatly across states.^[7]

Proponents of social justice contend that federalism has tended to obstruct national efforts to effectively even out these disparities.

The economic strategy of using race-to-the-bottom tactics in order to compete with other states in attracting new business growth also carries a social cost. For example, workers’ safety and pay can suffer as workplace regulations are lifted, and the reduction in payroll taxes for employers has led a number of states to end up with underfunded unemployment insurance programs. (cf. Alexander Hertel-Fernandez. 2012. “Why U.S. Unemployment Insurance is in Financial Trouble,” February. http://www.scholarsstrategynetwork.org/sites/default/files/ssn_basic_facts_hertel-fernandez_on_unemployment_insurance_financing.pdf)

Nineteen states have also opted not to cover more of their residents under Medicaid, as encouraged by the Patient Protection and Affordable Care Act in 2010, for fear it will raise state public spending and increase employers’ cost of employee benefits, despite provisions that the federal government will pick up nearly all cost of the expansion.^[8]

More than half of these states are in the South.

The federal design of our Constitution and the system of checks and balances has jeopardized or outright blocked federal responses to important national issues. President Roosevelt’s efforts to combat the scourge of the Great Depression were initially struck down by the Supreme Court. More recently, President Obama’s effort to make health insurance accessible to more Americans under the Affordable Care Act immediately ran into legal challenges^[9]from some states, but it has been supported by the Supreme Court so far. However, the federal government’s ability to defend the voting rights of citizens suffered a major setback when the Supreme Court in 2013 struck down a key provision of the Voting Rights Act of 1965.^[10]

No longer are the nine states with histories of racial discrimination in their voting processes required to submit plans for changes to the federal government for approval.

The benefits of federalism are that it can encourage political participation, give states an incentive to engage in policy innovation, and accommodate diverse viewpoints across the country. The disadvantages are that it can set off a race to the bottom among states, cause cross-state economic and social disparities, and obstruct federal efforts to address national problems.
